Coronary Heart Disease
Date: 2026-07-01
When the following symptoms appear during activity, improve with rest, and gradually become more frequent, it is important to consider whether there may be an issue with reduced blood flow to the heart.
  • A feeling of pressure or tightness in the chest when walking quickly or going upstairs
  • Occasional chest tightness that eases with rest, but keeps coming back
  • Shortness of breath during activity, with a noticeable drop in stamina
  • Intermittent palpitations or chest discomfort that is difficult to describe clearly
  • Symptoms are often dismissed as fatigue or stress, without further investigation

The key issue in coronary heart disease is not a brief episode of discomfort, but the ongoing effect of gradually narrowed coronary arteries on the heart muscle’s blood supply.

1 | How does modern medicine view coronary heart disease?

Coronary heart disease refers to narrowing or blockage of the coronary arteries that supply the heart, usually caused by atherosclerosis, resulting in insufficient blood supply to the heart muscle.

Its typical presentation is angina, with features such as:

  • Often triggered by activity, emotional stress, or exposure to cold
  • Presenting as chest pressure, tightness, heaviness, or pain
  • Pain may radiate to the left shoulder, arm, neck, or jaw
  • Symptoms may ease with rest or medication

Clinically, it is important to distinguish between:

Stable angina

Symptoms occur with activity and are relieved by rest; this is a relatively stable stage.

Acute coronary syndrome

Symptoms suddenly worsen, last longer, or even occur at rest. This may indicate a myocardial infarction and requires urgent treatment.

Common investigations include:
  • ECG (electrocardiogram)
  • Cardiac enzyme tests
  • Exercise stress testing
  • Coronary imaging examinations
If left uncontrolled for a long time, it may lead to:
  • Myocardial infarction
  • Arrhythmia
  • Heart failure

2 | Common modern medical approaches and when they are used

The main focus in treating coronary heart disease is to improve blood supply and reduce the risk of cardiovascular events.

Medication

This may include antiplatelet drugs, lipid-lowering medicines such as statins, blood pressure medicines, and vasodilators. These are used to reduce the risk of blood clots and myocardial ischaemia.

Lifestyle changes

Managing blood pressure, cholesterol, and blood glucose; quitting smoking; regular exercise; weight management; and stress control.

Interventional or surgical treatment

Such as coronary stenting or coronary artery bypass grafting. These are suitable for people with severe vessel narrowing or poorly controlled symptoms.

Long-term monitoring

Regular review of blood pressure, blood lipids, heart function, and overall risk status.

Anyone already diagnosed should continue medication and follow-up care. Do not stop medication on your own or delay treatment.

3 | How does traditional Chinese medicine understand this condition?

In traditional Chinese medicine (TCM), coronary heart disease is generally classified under Chest Bi syndrome and Heart Pain. The core issue is an imbalance involving deficiency at the root and excess in the manifestation.

Common TCM patterns include:
Qi deficiency as the root

Insufficient heart qi leads to weaker circulation.
Common signs include shortness of breath, fatigue, and poor exercise tolerance.

Yang deficiency

Insufficient warming and circulating force, often worse with cold or overexertion.
Common signs include chest tightness and sensitivity to cold.

Blood stasis

Poor blood circulation.
Common signs include chest pressure or a fixed, localised discomfort.

Phlegm and turbidity obstructing the channels

Often associated with high cholesterol and metabolic imbalance.
This may affect vessel patency and blood supply.

Emotional influence

Stress and mood changes affect the flow of qi and may trigger or worsen symptoms.

The focus of TCM support is to help regulate qi and blood flow, body constitution, and overall balance, rather than replace modern medical treatment for narrowed coronary arteries.

prime&naturals will assess the triggering situation, exercise tolerance, symptom features, and past medical history to identify the main factors behind the reduced blood supply.

Common patterns include:

Qi deficiency with blood stasis

Shortness of breath, fatigue, and chest tightness during activity.
Key focus: weak driving force plus poor blood flow.

Phlegm and turbidity obstructing the channels

More marked chest tightness, larger body build, and high cholesterol.
Key focus: metabolic imbalance and phlegm-turbidity affecting the vessels.

Heart yang deficiency

Cold intolerance and poor exercise tolerance.
Key focus: insufficient circulating force.

Qi stagnation with blood stasis

Symptoms become more obvious under stress.
Key focus: emotional strain affecting qi flow.

Qi and yin deficiency

Long-term, chronic condition with reduced physical energy.
Key focus: reduced overall regulatory capacity.

The core of pattern differentiation is to identify:

  • Whether reduced blood supply is the main issue
  • Whether metabolic burden and vascular strain are contributing factors
  • Whether stress and emotional triggers are involved

5 | prime&naturals treatment approach

In the management of coronary heart disease, our role is to support treatment within the framework of modern medical care, while helping to improve factors that affect circulation and overall stability.

Key goals include:

  • Improving the flow of qi and blood
  • Supporting heart qi and physical stamina
  • Addressing metabolic imbalance and phlegm-turbidity
  • Reducing the impact of stress and emotional triggers
  • Establishing a long-term management routine

Treatment may include, depending on the individual:

  • Chinese herbal medicine
  • Acupuncture
  • Lifestyle advice

This should be used alongside existing Western medical treatment.

6 | When to consider TCM support

After necessary cardiac assessment has been completed and acute risk has been ruled out, TCM support may be considered if the following are present:

  • Repeated chest tightness or shortness of breath after activity
  • Diagnosed coronary heart disease, but ongoing fatigue or recurrent discomfort
  • Co-existing high blood pressure, high cholesterol, or blood sugar issues
  • Symptoms clearly affected by stress or poor sleep
  • A wish to improve overall wellbeing alongside standard treatment

Clinical priorities are:

  • Whether the condition has entered a long-term management stage
  • Whether there are constitutional and regulatory factors that can be improved

However, urgent medical care is needed immediately if the following occur:

  • Chest pain that continues and does not ease
  • Pain spreading to the arm, jaw, or back
  • Cold sweats, shortness of breath, nausea, or marked weakness
  • Chest pain at rest, or sudden worsening of symptoms

The core of coronary heart disease management is to first rule out acute risk, then carry out long-term adjustment. With proper medical care, and through overall regulation and lifestyle management, daily stability may be better maintained.
